DRAWERFLOCK.

Specification of Letters Patent.

Patented Apr. *7, 1914.

Application filed May 7, 1913. Serial No. 766,113.

the like.

The object of the invention is to provide a locking device for drawersof various character, which shall be capable of making a secret lockwith a drawer by the movement of the drawer, and which shall hold thedrawer locked in open position as well as in closed position.

A further object of the invention is to provide a spring controlleddrawer lock of such novel and peculiar construction and arrangement .ofparts as to be operated by the drawer during the inward movement of thedrawer for locking the drawer, and as to be operated from without thedrawer casing for unlocking the drawer. Such lock is adapted to hold thedrawer open in various positions.

With these and various other objects, advantages and improved results inview, the invention consists in the special construction and arrangementof parts, as will be hereinafter fully described and set forth in theappended claim.

In the accompanying drawings forming part of this application :Figure 1is an inverted perspective view of a drawer casing exemplifying thisinvention. Fig. 2. is an enlarged sectional view of a drawer in lockedposition. Pg. 3 is a similar view of Y the drawer casing with the drawerremoved.

Fig. 4 is a detaiLperspective View of the locking device. Fig. 5 is anenlarged vertical sectional view of the locking device.

'The same reference characters denote the same parts throughout theseveral views of the drawings.

For the purpose of exemplifying the ap-' plication of the lockingdevice, I have selected a drawer such as may be found associated withthe pigeon holes of a roll-top desk, but the lock is. quite asapplicable to various other drawers, such as are found in dentalcabinets, file cases and the like. The drawer shown in the drawingscomprises a front 1, back 2, sides 3, and bottom 4:. Such drawer fits acasing formed by sides 5, a bottom 6, and top 7. v The outer face of thebottom 4: of the drawer is provided with a metal plate 8, having aplurality of catch-holes 9 therein, the function of which will behereinafter explained. The bottom 6 of the casing has an aperture 10,over which the plate 8 slides in the sliding movement of the-drawer sothat the holes "9 may successively register with the aperture 10.

The locking device is suspended from the outer face of the bottom 40fthe casing by means of a plate spring 11 having one end secured to saidface at 12, and having an aperture 13 in the free end thereof. Thelocking device comprises a screwthreaded pin 14, having a milled head15, and te'rminating in a beveled end 16, and nuts 17 and 18 forclamping the free end of the spring 11 on the pin, and by means of whichthe pin may be adjusted. The beveled portion of 'the pin projectsthrough the casing aperture 10 so as to stand in the path of themovement of the drawerplate holes 9, and under pressure of the springthe pin end is forced into one or another of the holes 9. When it isdesired to unlock the drawer, the pin is pulled sufliciently todisengage the beveled end of the pin with the catch-holes, and the pinis held in depressed position during withdrawal or may be released. Itwill be seen that the pin is depressed during the inward movement of thedrawer by the bottom of the drawer pressing against the beveled end ofthe pin so as to permit the drawer to be closed and automaticallylocked.

In order to vary the extent of the projecting portion of the pin throughthe bottom of the drawer casing as desired or as occasion may demand,the lock nuts 17 and 18 are operated so as to clamp the spring to thepin according to the length of projection required.

It is obvious that the lock may be applied to one side or the other of adrawer casing with the same results as hereinbefore stated, that thelock may be duplicated or multiplied according to the size of thedrawers to which the lock may be applied, and that while I have shownand described the lock 110 applied to a desk drawer, I do not restrictor confine myself in'the application of the lock.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

In a drawer operated lock,- the combination with a drawer, a drawerplate having movement of the drawer, an adjustable screw pin suspendedby the free end of the spring and cooperating with the holes and the 1aperture, and means for adjustably clampin the spring to the pin.

witness whereof I hereunto --set my hand in the presence of twowitnesses.
